Power grid maintenance plan compilation optimization method and device and computer readable storage medium

The invention discloses a power grid maintenance plan compilation optimization method and device and a computer readable storage medium. The method comprises the following steps: acquiring an initialfailure rate matrix of power grid equipment to be overhauled; updating the initial failure rate matrix based on the power grid equipment maintenance plan to obtain an updated failure rate matrix; obtaining a power grid equipment maintenance optimization model, and calculating a power grid operation risk change value according to the power grid equipment maintenance optimization model, the initialfault rate matrix and the updated fault rate matrix; judging whether the power grid operation risk change value meets convergence judgment or not; and if the power grid operation risk change value does not meet the convergence judgment, updating the power grid equipment maintenance plan, and returning to execute the step of updating the initial failure rate matrix until the power grid operation risk change value meets the
